SDelay timing doesn't change with tempo [FIXED in 2.1.0]

An old bug from 1.0 (and earlier) that seems to still persist, is that changing the playback tempo doesn't change the timing on the SDelay contraption when it's set to semiquavers. The only way to update the delay time is to change the delay units to milliseconds and then back. I realize most people probably don't go changing the tempo while a file is playing..
